  1. 1. Deep Eutectic Solvents and Their Possible Application in Transdermal Drug Delivery

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sarah Lindblom; [2020]
    Nyckelord :Deep Eutectic Solvents; Pharmaceuticals; Transdermal drug delivery; Choline Chloride; Rheology; Formulation; BSA; Franz cell diffusion; Pharmaceutical technology; Läkemedelsteknologi; Technology and Engineering;

    Sammanfattning : Deep eutectic solvents, DES, is a type of solvent made by mixing a quaternary ammonium salt with a hydrogen bond donor at the eutectic point of the system. Most common quaternary ammonium salt is Choline Chloride, ChCl. A specific DES, Choline:CAGE has shown promise in delivering insulin through the skin of mice. LÄS MER

  3. 2. Nanoparticle loaded hydrogels as a pathway for enzyme controlled drug release in ophthalmic applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Michelle Åhlén; [2017]
    Nyckelord :nanoparticles; ophthalmic drug delivery; chitosan; polyacrylic acid; FITC;

    Sammanfattning : The aim of this study was to develop nanoparticle loaded hydrogel based contact lenses that could be used for ocular drug delivery. Two potential contact lens platforms for controlled ophthalmic drug delivery was thus developed by incorporating chitosan-poly(acrylic acid) nanoparticles into polyvinyl alcohol (PVA) hydrogels and nanoparticles together with cellulose nanocrystals (CNC) in PVA.

  4. 3. Feasibility of lignocellulose as feedstock for biological production of super absorbent polymers

    Master-uppsats, Teknisk biologi; Linköpings universitet

    Författare :Christoffer Nystrand; [2010]
    Nyckelord :3-HP; 3-hydroxipropionic acid; SAP; superabsorbent polymer; lignocellulose;

    Sammanfattning : Super absorbent polymers (SAP) can absorb liquid many times its own weight and is used in diapers and incontinence pads. The most common type of SAP is cross-linked polyacrylic acid. The production of acrylic acid uses crude oil as starting material. LÄS MER
